Sorensen XDL56-4 DC Power Supply

Overview

The Sorensen XDL56-4 is a single-output linear DC power supply delivering precision power for laboratory and bench test applications. It features multiple selectable voltage and current ranges to optimize resolution and headroom for different circuit requirements. Using 16-bit DACs, the supply achieves 1mV voltage resolution and calibration-grade accuracy. The pure linear design delivers superior regulation, low output noise, and excellent transient response—ideal for sensitive analog circuits and measurement equipment.

The advanced user interface supports both direct numeric entry and incremental rotary control, with illuminated keys and display legends for intuitive operation. Comprehensive protection features and non-volatile memory storage of up to 50 power supply configurations provide safety and convenience for repeated measurements.
